Properties of Rational Functions

3. OBJECTIVE 1

4. { x | x ≠ -2 , x ≠ -6 }
{ x | x ≠ -4 }
All Reals
All Reals
{ x | x ≠ -2 }

13. OBJECTIVE 2

15. x = - 3
x = 2 and x = - 2
x = - 1 and x = - 4
x = 2

16. OBJECTIVE 3

17. A rational function R(x) is proper if the degree of the
numerator is less than the degree of the denominator.

18. y = 0 is the horizontal asymptote
Degree of numerator < degree of denominator
y = 0 is the horizontal asymptote

19. 2 Degree of numerator = degree of denominator , y = 2x2 /x2 = 2 y = 2
___________________
Degree of numerator = degree of denominator , y = 2x2 /x2 = 2

20. Degree of numerator = degree of denominator , y = 5x6 /2x6 = 5/2

21. x + 6
Oblique Asymptote is y = x + 6
